At least three people were killed when gunmen in Haiti opened fire on medical staff, police and journalists during a briefing to announce the reopening of the country's largest public hospital.
Many others were injured in Tuesday's attack at the general hospital in the capital, Port-au-Prince.
Photos posted online appeared to show several injured or dead inside the building.
The site was taken over by the Haitian government in July after it was occupied and destroyed by violent gangs that control much of the city.
Journalists were waiting for the health minister to arrive when the shooting began.
According to reports, two journalists and a policeman were shot dead.
In a statement, Haiti's transitional presidential council vowed to punish the perpetrators.
“We express our sympathy to all the families of the victims, in particular to the Haitian National Police and all journalistic associations,” the council said.
The people of Haiti continue to suffer intolerable levels of gang violence, despite the installation of a new transitional government in April and the deployment of an international force led by Kenyan police six months ago.
Haiti has been engulfed in a wave of gang violence since the 2021 murder. of the then President Jovenel Moise.
Approximately 85% of Port-au-Prince is still under gang control.
The UN says around 5,000 people have been killed in violence in Haiti this year and the country is now on the brink of collapse.
